Firefox has singlehandedly, in my opinion, changed the internet browsing experience. Never before has it been so easy and so much fun to peruse through your favorite sites and find new content.
Firefox has the ability to allow "add-ons" (which are simply different tools) to customize its usefulness for each and every user. It's a browser that can be unique as each and every user!
Five awesome plug-ins you need? I'll tell you!
- Dictionary: This add-on provides real-time spell checking ANYWHERE you insert test throughout the browser. Whether it's a comment box, a post, or an email, the dictionary will notify you immediately with a dotted red line below the questionable word. Download it here.
- Colorful tabs: Okay so it's not entirely that helpful, but it's FUN! Each open tab is given a different color, which helps with navigation and deciphering one tab from another. You should totally have this one, even if its sole purpose is to make your browser pretty!
- Greasemonkey: This is a script-based plugin that allows you to add scripts created by users to enhance services. Greasemonkey is an amazing tool which has totally changed how I surf the net and work online. There's scripts based on improving and customizing anything, from Gmail to replying to comments where you're a website administrator. There's even a Greasemonkey add-on to improve Flickr! If you're so inclined to try Greasemonkey, Userscripts is also a site that has numerous other scripts.
- Undo Closed Tabs: Ever close a tab by accident and forget how you got to that site? This add-on creates a history of recently closed tabs so you can get that site back in a jiff! Save time and aggrevation.
- Cooliris Previews: Ever curious about a link, but you don't want to navigate from the page you're at? Cooliris Preview is just for you! All you have to do is hover over the little icon that appears when your cursor is on a link – and the link will pop-up in a new window. If you're interested, you can click to open it in a new tab, or just peruse it in the Cooliris Preview window.
So there you have it. Five awesome Firefox add-ons – and if you're not using Firefox? You're dead to me. Let's discuss why you should change! If these add-ons were enough to convice you, go here and get it NOW!

For #4, it's already built into FF. It's in History/Recently Closed Tabs.
#1 is built in as well. You can get different dictionaries, but there is a basic one.
I agree on Colorful Tabs, though. I love that one!! Doesn't work with all themes, though.
My favorites are Twitter Fox, Better GReader, Remember the Milk for gmail, delicious bookmarks and add to Wishpot! I'm totally going to try out the colorful tabs though!
